Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering and chemical equipment technology, specifically to a plastic particle stirring chamber structure with spiral guide vanes. Background Technology
[0002] Existing plastic pellet mixing devices play a crucial role in industrial production, and their performance directly affects the quality of the final product and production efficiency. However, traditional mixing devices often have many shortcomings and urgently need improvement. Currently, the most common plastic pellet mixing devices on the market mainly adopt simple planar mixing blades or fixed blade structures. These structures are relatively simple in design and have low manufacturing costs, but they have exposed many problems in practical applications. Among them, the most prominent problem is that the plastic pellets are unevenly distributed in the cavity during the mixing process, which greatly reduces the mixing effect.
[0003] Specifically, because the mixing method of planar or fixed blades is relatively simple and lacks effective control over the fluid dynamics characteristics in the mixing area, plastic particles are prone to local aggregation or retention during the mixing process. These problems are particularly serious when mixing high-speed rotating or high-viscosity materials. Material retention and uneven mixing not only lead to insufficient heating or mixing of plastic particles, affecting the quality of the final product, but also reduce production efficiency and increase production costs.
[0004] To address the aforementioned issues, researchers and engineers have begun exploring more efficient mixing structures in recent years. Among these, mixing structures with helical guide vanes have gradually gained attention. This new type of mixing structure adds helical guide vanes to the traditional mixing chamber. The design of the helical guide vanes can effectively guide plastic particles to flow along a helical trajectory within the chamber, thereby achieving a more uniform and thorough mixing effect.
[0005] However, most of the discharge ports in the mixing chamber structure are fixed. The fixed discharge port design may cause materials to accumulate in certain areas, resulting in poor mixing and blending effects in some areas. Furthermore, the fixed position of the discharge port restricts the freedom of material flow, leading to uneven mixing effects. Utility Model Content
[0006] The purpose of this invention is to provide a plastic particle stirring chamber structure with spiral guide vanes to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a plastic granule mixing chamber structure with spiral guide vanes, comprising a mixing chamber machine, a storage box on the left side of the mixing chamber machine, a feeding cylinder connected to the outside of the storage box, a connecting plate fixedly connected to one end of the feeding cylinder, a cover plate fixedly connected to the top of the mixing chamber machine, an arc-shaped groove in the cover plate, a reciprocating structure fixedly connected to the front of the cover plate, spiral vanes inside the mixing chamber machine, a guide rod rotatably connected inside the cover plate, the guide rod being connected to the reciprocating structure, a discharge plate fixedly connected to the outside of the guide rod, a limit rod fixedly connected to the other side of the discharge plate, several baffles rotatably connected inside the discharge plate, an adjustment structure outside the discharge plate, the adjustment structure being connected to the baffles, the adjustment structure including a threaded rod, a gear, and a motor, an L-shaped plate externally threaded onto the threaded rod, a toothed plate fixedly connected to one side of the L-shaped plate, and a coil spring on one side of the gear.
[0008] As a further preferred embodiment of this technical solution, the connecting plate is connected above the cover plate, the limiting rod is slidably connected in the arc-shaped groove, and the guide rod is rotatably connected in the cover plate.
[0009] As a further preferred embodiment of this technical solution, the threaded rod is rotatably connected to the outside of the feed plate, the motor is fixedly connected to the outside of the feed plate, and the output shaft of the motor is connected to the threaded rod.
[0010] As a further preferred embodiment of this technical solution, the first gear is fixedly connected to one side of the baffle, the first gear is connected to the feed plate through a coil spring, and the toothed plate meshes with the first gear.
[0011] As a further preferred embodiment of this technical solution, the reciprocating structure includes a fixed frame and a second gear. The fixed frame is fixedly connected to the outside of the cover plate, the second gear is fixedly connected to one end of the guide rod, and a positioning rod is fixedly connected to the right side of the fixed frame.
[0012] As a further preferred embodiment of this technical solution, the positioning rod is rotatably connected to a concave plate and a half gear, the concave plate is connected to the half gear, the half gear meshes with a gear, and a rotating plate is rotatably connected inside the fixing frame.
[0013] As a further preferred embodiment of this technical solution, the rotating plate is slidably connected inside the concave plate, and a second motor is fixedly connected to the left side of the fixing frame, with the output shaft of the second motor connected to the rotating plate.
[0014] This utility model provides a plastic particle stirring chamber structure with spiral guide vanes, which has the following beneficial effects:
[0015] (1) This utility model sets up a feeding cylinder, a connecting plate, a feeding plate and an adjusting structure. The motor drives the threaded rod to rotate, and the L-shaped plate moves on the surface of the threaded rod. When the toothed plate contacts the gear, the baffle will flip with the gear and the coil spring will deform accordingly. When the toothed plate contacts the left side of another set of baffles, the first set of baffles will reset through the coil spring when it loses resistance. The mixing chamber structure, through the cooperation between the threaded rod, toothed plate, gear and coil spring, enables multiple baffles in the feeding plate to unfold in sequence, so that the raw materials can be fed in different positions, avoiding the phenomenon of raw materials gathering in certain areas, thereby ensuring the uniformity of the mixing effect.
[0016] (2) By setting a reciprocating structure, the rotating plate is driven by the second motor to rotate. The rotating plate slides in the concave plate. The half gear swings around the positioning rod as the action of the concave plate. Since the half gear meshes with the second gear, the feeding plate will reciprocate around the guide rod. The feeding plate can realize the function of reciprocating swing in the cover plate, which is convenient for feeding the internal raw materials and avoids the raw materials from accumulating inside the feeding plate.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown, in this embodiment, a plastic granule mixing chamber structure with spiral guide vanes includes a mixing chamber machine 1. A storage tank 3 is provided on the left side of the mixing chamber machine 1, and a feed cylinder 4 is connected to the outside of the storage tank 3. A connecting plate 5 is fixedly connected to one end of the feed cylinder 4. A cover plate 2 is fixedly connected to the top of the mixing chamber machine 1. An arc-shaped groove 11 is opened in the cover plate 2. A reciprocating structure 7 is fixedly connected to the front of the cover plate 2. Spiral vanes 12 are provided inside the mixing chamber machine 1. A guide rod 8 is rotatably connected inside the cover plate 2. The guide rod 8 is connected to the reciprocating structure 7. Structure 7 is connected to the guide rod 8 and a feeding plate 9 is fixedly connected to the outside. A limit rod 10 is fixedly connected to the other side of the feeding plate 9. Several baffles 13 are rotatably connected inside the feeding plate 9. An adjustment structure 6 is provided outside the feeding plate 9. The adjustment structure 6 is connected to the baffles 13. The adjustment structure 6 includes a threaded rod 601, a gear 602 and a motor 603. An L-shaped plate 604 is externally threaded to the threaded rod 601. A toothed plate 605 is fixedly connected to one side of the L-shaped plate 604. A coil spring 606 is provided on one side of the gear 602.
[0024] like Figure 1 and Figure 3 As shown, the connecting plate 5 is connected above the cover plate 2, the limiting rod 10 is slidably connected in the arc groove 11, the guide rod 8 is rotatably connected in the cover plate 2, the threaded rod 601 is rotatably connected to the outside of the feed plate 9, the motor 603 is fixedly connected to the outside of the feed plate 9, the output shaft of the motor 603 is connected to the threaded rod 601, the gear 602 is fixedly connected to one side of the baffle 13, the gear 602 is connected to the feed plate 9 through the coil spring 606, and the toothed plate 605 meshes with the gear 602.
[0025] By setting a coil spring 606, when the L-shaped plate 604 moves on the surface of the threaded rod 601, the toothed plate 605 will contact the gear 602. Then the coil spring 606 will deform as the gear 602 rotates, so that the coil spring 606 provides a certain support for the rotation of the gear 602. When the gear 602 loses resistance, it will be reset by the coil spring 606.
[0026] like Figure 4As shown, the reciprocating structure 7 includes a fixed frame 701 and a second gear 706. The fixed frame 701 is fixedly connected to the outside of the cover plate 2, and the second gear 706 is fixedly connected to one end of the guide rod 8. A positioning rod 703 is fixedly connected to the right side of the fixed frame 701. A concave plate 704 and a half gear 705 are rotatably connected to the outside of the positioning rod 703. The concave plate 704 is connected to the half gear 705, and the half gear 705 meshes with the second gear 706. A rotating plate 702 is rotatably connected inside the fixed frame 701. The rotating plate 702 is slidably connected inside the concave plate 704. A second motor 707 is fixedly connected to the left side of the fixed frame 701. The output shaft of the second motor 707 is connected to the rotating plate 702.
[0027] By setting a positioning rod 703, the rotating plate 702 is driven to rotate by the motor 707. The rotating plate 702 slides inside the concave plate 704. The half gear 705 swings around the positioning rod 703 as the concave plate 704 moves. This allows the positioning rod 703 to guide the rotation of the concave plate 704 and the half gear 705, preventing them from falling off during rotation.
[0028] This utility model provides a plastic particle stirring chamber structure with spiral guide vanes, and its specific working principle is as follows:
[0029] When the mixing chamber structure is mixing the raw materials, the raw materials in the storage tank 3 can be conveyed through the feed cylinder 4 and the connecting plate 5. The raw materials will fall into the discharge plate 9. The rotating plate 702 will be driven by the motor 707 to rotate. The rotating plate 702 will slide in the concave plate 704. The half gear 705 will swing around the positioning rod 703 as the concave plate 704 acts. Since the half gear 705 meshes with the gear 706, the discharge plate 9 will reciprocate around the guide rod 8.
[0030] Then, the threaded rod 601 is rotated by the motor 603, and the L-shaped plate 604 moves on the surface of the threaded rod 601. When the toothed plate 605 contacts the gear 602, the baffle 13 will flip with the gear 602, and the coil spring 606 will deform accordingly. When the toothed plate 605 contacts the left side of another set of baffles 13, the first set of baffles 13 will be reset by the coil spring 606 when it loses resistance. Then, the raw material will be fed through the baffles 13 that unfold in sequence in the feeding plate 9, and then stirred by the spiral blades 12.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
